Manufacturing Quality Control of 2-Bromo-3-butyl thiophene
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detection | Quantifies main component peak area relative to calibration standard using flame ionization detection. |
| Related Substances | High Performance Liquid Chromatography (HPLC) with UV detection | Separates and quantifies impurities based on retention time and UV absorbance at specified wavelength. |
| Residual Solvents | Gas Chromatography (GC) with Headspace sampling | Detects and quantifies volatile organic solvents by equilibrium partitioning into headspace gas phase. |
| Water Content | Karl Fischer Titration | Measures water via stoichiometric reaction between iodine, sulfur dioxide, and water in pyridine/methanol medium. |
| Heavy Metals | Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES) | Quantifies metal impurities (e.g., Pb, Cd, Hg, As) by atomic emission intensity after plasma atomization. |
| Chloride Impurity | Ion Chromatography (IC) | Separates and detects chloride ions based on anion exchange retention and conductivity detection. |
| Residue on Ignition | Gravimetric analysis | Measures non-volatile inorganic residue after high-temperature ashing and weighing. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range at which solid transitions to liquid based on optical observation of crystal collapse. |
| Specific Optical Rotation | Polarimetry | Measures rotation angle of plane-polarized light induced by chiral molecules in solution. |
| Appearance | Visual Inspection | Assesses physical state, color, and clarity against established reference standards under controlled lighting. |
| Acid Value | Acid-Base Titration with NaOH | Quantifies acidic impurities by titration with standardized sodium hydroxide solution using phenolphthalein indicator. |
| Bulk Density | Tap Density Measurement | Determines mass per unit volume after standardized mechanical tapping of a powder sample in a calibrated cylinder. |
